Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 917BF524 is determined by strict alignment with the following core parameters:

Mandatory Matching Parameters:

• Connector Style: SMA
• Connector Type: Jack, Female Socket
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Solder
• Mounting Type: Panel Mount
• Mounting Feature: Flange
• Fastening Type: Threaded
• Dielectric Material: PTFE
• Number of Ports: 1

Allowable Variation Parameters:

• Frequency - Max: Substitute must support minimum 12.4 GHz (within 0.1 GHz tolerance of main part specification)
• Center Contact Material: Brass or Phosphor Bronze acceptable
• Body Material: Brass
• Center Contact Plating: Gold
• RoHS Status: RoHS Compliant or ROHS3 Compliant
• MSL: 1 (Unlimited)
• ECCN: EAR99

The substitute part PCB.SMAFST.2H.A.HT from Taoglas Limited meets all mandatory parameters and operates within allowable frequency variation, qualifying it as a direct substitute for the 917BF524.

Parameter Comparison

Engineering Selection Recommendations

Both the 917BF524 and PCB.SMAFST.2H.A.HT are active production parts with full regulatory compliance. The 917BF524 maintains RoHS compliance, while the PCB.SMAFST.2H.A.HT meets the more stringent ROHS3 standard. Both parts carry EAR99 export classification and MSL 1 moisture sensitivity rating, indicating no special storage or handling requirements.

The frequency specification difference of 0.1 GHz (12.5 GHz versus 12.4 GHz) falls within acceptable tolerance for SMA connector applications and does not restrict substitution in standard RF circuit designs operating below 12.4 GHz.

The center contact material variation (Brass versus Phosphor Bronze) reflects different manufacturing approaches by each supplier. Both materials with gold plating provide equivalent electrical performance and contact reliability for solder-terminated connections.

Packaging differences (Winchester Interconnect standard packaging versus Taoglas Limited tray packaging) do not affect electrical or mechanical compatibility and relate only to logistics and inventory handling.

Frequently Asked Questions (FAQ)

Q: Can PCB.SMAFST.2H.A.HT replace 917BF524 in existing designs?

A: Yes. Both connectors share identical connector style, type, impedance, termination method, mounting configuration, and dielectric material. The 0.1 GHz frequency difference and alternative center contact material do not affect functional compatibility in applications operating within the 12.4 GHz specification of the substitute part.

Q: What is the significance of the frequency specification difference?

A: The 917BF524 specifies 12.5 GHz maximum frequency, while PCB.SMAFST.2H.A.HT specifies 12.4 GHz. This 0.1 GHz difference is within standard manufacturing tolerance for SMA connectors and does not restrict substitution for applications operating at or below 12.4 GHz.

Q: Are there differences in solder joint reliability between Brass and Phosphor Bronze center contacts?

A: Both materials with gold plating provide equivalent solder wettability and joint reliability. The material selection reflects supplier manufacturing standards and does not impact electrical performance or mechanical durability in solder-terminated applications.

Q: Does packaging format affect connector performance?

A: No. Packaging format (standard versus tray) relates only to logistics, storage, and handling. Electrical and mechanical specifications remain identical regardless of packaging method.

Q: Are both parts suitable for high-temperature applications?

A: The 917BF524 specifies operating temperature range of -65°C to 165°C. Operating temperature specification for PCB.SMAFST.2H.A.HT is not provided in the available data. For applications requiring confirmed high-temperature performance, the 917BF524 specification should be referenced.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate restriction of hazardous substances. ROHS3 represents the current regulatory standard. Both parts meet environmental compliance requirements for their respective markets.

Q: Can these connectors be used interchangeably in PCB assembly?

A: Yes. Both connectors feature identical panel-mount flange configuration, threaded fastening, and solder termination. PCB footprint and assembly procedures remain unchanged between the two parts.
